I didn't realize UncleDuncan had altered your LNM note to say X... I thought your original post said X. Just looked back and saw that you did indeed say LNM, so now I am fully untwisted and far less dizzy than I was. Got it!
I agree that LNM is (IMO) a top 5 Arrow coaster for that sort of visual-cultural impact. I think I'd put Matterhorn, Space Mountain, and Big Thunder Mountain above it, even though I tend to stay away from those parks. But outside the Disney parks, I dunno... I'd still put Magnum at least on par because it is not only iconic in its own right as That Gigantic Red Lakeside Coaster, but also ushered in a very particular style of ride that forever changed the skyline of nearly every major regional park in America. Its reach is long and literally massive. Those are probably the full list, though. Can't think of any others.
To me, LNM is as close as anything gets to being the "perfect" Arrow looper. Still novel; highlights nearly everything Arrow did well at the time; avoids most things Arrow stunk at; tall enough to thrill; short enough to avoid Arrow's later-stage megalooper problems; no complex curves or twisting inversions (but I repeat myself); and to this day it's still a damned good airtime machine.
